See <a rel="nofollow" class="external text" href="https://web.archive.org/web/20100923200157/http://user.cs.tu-berlin.de/~nowozin/autopano-sift/">archiv.org version of the autopano sift page</a> for details.
</p><p>Functionally, <b>autopano-sift</b> is very similar to <a href="Autopano.html" title="Autopano">autopano</a> and the two can be used interchangeably to a certain extent.
</p><p>There are both command-line and GUI versions of autopano-sift.  There is a tutorial for Using Autopano-SIFT With PTGui<a class="external" href="https://wiki.panotools.org/Using_Autopano-SIFT_With_PTGui">[*]</a>.
</p><p>Autopano-sift is Open Source and written using C# and mono. The use of the Scale-invariant feature transform<a class="external" href="http://www.wikipedia.org/wiki/SIFT">[*]</a> algorithm is restricted by US Patent 6,711,293 awarded March 23, 2004 to the University of British Columbia. 
</p><p>Autopano-sift has been largely superseded by a C port called <a href="Autopano-sift-C.html" title="Autopano-sift-C">autopano-sift-C</a>, available from the <a href="Hugin.html" title="Hugin">hugin</a> project.
